Really aggro guy postflop to this point, and he hadn't folded to multiple 3b to this point. Might be bad to do this.

flat pre
bet flop

KJ not that much of a 3b, but plenty good to call. slightly more of a 3b if btn opens 3x or pot. I think it's ok as a low freq 3b if you want.
small range cb is a good and easy way to profitably play flop with no reads on your opp that would make you deviate

the problem with x/r is your tp is on the weaker side and doesn't beat some of his top pairs and you inadvertently isolate yourself against the stronger part of his range, which is not what you want to do with a medium strength hand.

had the flop been K73hh, the x/r would've been more reasonable, as he's now potentially continuing with some extra gutshots and weak pairs

another concern is how you construct your cb range on this flop, you're going to x/r good top pairs, AA/KK and what else? few fds? it's a bit transparent
and then you x/c QQ-88? transparent and easy to play against as well
this hand would have fit much better into your x/c range (had you any reasons to deviate from the cb in the first place), to protect your underpairs from stabs on flops and turns

I wasn't really thrilled about it when I did it, and not normally a hand that I 3b.
